Learn how long brake rotors should last, when to replace rotors, and whether you need new rotors when replacing brake pads. Help keep your Subaru ready with expert brake service.
Your Subaru’s braking system is built for reliability, whether you’re navigating city streets, rugged trails, or winding mountain roads. But even the toughest brakes wear down over time, especially the rotors. If you’ve been wondering what rotors are and when to replace them, you’re in the right place. Let’s break it all down so you can stay ready for any adventure.
Brake rotors are the large metal discs behind your wheels. When you press the brake pedal, the pads clamp down on the rotors to slow your vehicle. This process generates intense heat and friction, which wears down both the pads and the rotors over time.
Healthy rotors provide smooth, controlled braking, but when they become too thin, warped, or damaged, they can reduce stopping power and compromise your vehicle’s performance.
On average, brake rotors last between 50,000 and 70,000 miles, but many factors influence their lifespan, including:
Regular brake maintenance and inspections are the best way to determine if your rotors are still in good shape.
Unlike brake pads, which wear out more quickly, rotors don’t need to be replaced as often. However, they should be inspected when replacing brake pads. If your rotors show excessive wear, deep grooves, or warping, it’s probably time for a replacement.
Your Subaru owner’s manual will have specific guidelines, but generally, check your rotors every 15,000–30,000 miles and replace them as needed.
Not always. If your rotors are in good condition — smooth, free from warping, and still thick enough — you can replace just the brake pads.
However, worn-down rotors won’t allow new brake pads to make full, even contact, which can reduce braking efficiency and cause premature wear on your new pads. Many Subaru owners choose to replace rotors and brake pads together to maximize performance.
If you’re experiencing any of the following symptoms, your rotors might be due for replacement.
Unusual braking noises, such as squeaking, screeching, or grinding, can indicate that your rotors are worn, uneven, or have deep grooves.
If you feel a shake in your steering wheel when braking, your rotors may be warped or have uneven wear, causing the brake pads to grip inconsistently.
A pulsing or vibrating brake pedal is another telltale sign of uneven rotor wear. If braking feels unsteady, it’s time for an inspection.
When rotors become too thin, they can’t dissipate heat properly, leading to longer braking distances.
Excessive heat can cause rotor discoloration, turning them blue, purple, or dark brown. Heat damage can lead to warping and reduced braking effectiveness.
Light rust on rotors is normal if your car sits for a few days, but excessive corrosion can weaken the rotors and require replacement.
If you can feel deep ridges on your rotors, they’re likely too worn to function properly.
If your Anti-lock Braking System (ABS) light comes on, your vehicle may be experiencing braking system issues, including rotor wear.
You shouldn’t drive with bad rotors. Worn or warped rotors reduce braking efficiency, increase stopping distance, and make your Subaru’s handling unpredictable — especially in wet or off-road conditions. If you suspect an issue, don’t wait! Schedule a brake inspection at Hicks Family Subaru today.
